Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Mingjiada Electronics offers STMicroelectronics' L9935013TR two-phase stepper motor driver in stock. This driver is specifically designed for stepper motor applications requiring high precision, low noise, and high efficiency, and is widely used in industrial automation, robotics, 3D printing, and various precision control fields.

Product Description

The L9935013TR is a high-performance two-phase stepper motor driver that employs advanced microstepping technology to achieve high-precision position control and speed control. The driver supports multiple operating modes, including full step, half step, and microstep, to meet the needs of different application scenarios. Its built-in intelligent power management functionality effectively reduces energy consumption and improves system efficiency.

 Core Features

✅ High-integration design

Built-in 4-channel half-bridge (H-bridge) for direct driving of bipolar stepper motors.

Integrated DMOS power stage with 400mΩ on-resistance to reduce power consumption.

✅ SPI Digital Control

Current, speed, and microstep mode can be set via the SPI interface, simplifying system design.

Supports full step and half step modes.

✅ Multiple Protection Mechanisms

Over-temperature protection (TSD): automatically shuts down when junction temperature exceeds 150°C.

Under-voltage lockout (UVLO): Prevents misoperation due to low voltage.  

Cross-conduction protection: Prevents direct short circuits between the upper and lower bridge arms.

✅ Automotive-grade reliability  

Operating temperature range: -40°C to +150°C, suitable for harsh environments.  

Compliant with RoHS standards, lead-free packaging.

✅ Low External Component Requirements  

Integrated LDO and drive logic reduce the complexity of peripheral circuit design.
